For four years the number 21 has been Ricardo Allen, but now that he is gone it is reserved for two players.
Dolapo Macarthy - Sr.
Merrillville, IN (Merrillville HS)
6'5", 229 pounds
2014 Projection: Contributor at Tight End
Macarthy has been all over the place. He went to Hargrave Military Academy out of high school and came to Purdue as a quarterback. In fact, out of Merrillville HS he was the No. 15 dual-threat QB in the nation. He eventually ended up at Purdue as a walk-on and switched to wide receiver. As a sophomore in 2012 he stepped on the scene and had 28 receptions for 252 yards and a score.
With those numbers, especially since most of them came late in the season, it was thought he would be one of Purdue's top receivers last year. Instead, he had a single catch for five yards against Notre Dame. Now he is a tight end, where his size is hoped to be an asset as a solid contributor in his final year.
Cedric Dale - Fr.
Dalls, TX (Hebron HS)
5'9", 170 pounds
2014 Projection: possible redshirt
Dale has been doing well in fall camp so far, but Purdue may still see him redshirt because there are plenty of good defensive backs ahead of him. He is a three-star prospect from Dallas that was originally a running back, so if he gets the ball in his hands he knows what to do with it. As one of Purdue's last commits in the 2014 class, he was a good pickup.
